1. Even though the electromechanical relay has served well for many generations, the ever-increasing sophistication and complexity of modern processing equipment requires faster acting, more reliable control functions than electromechanical relays and/or timing devices can offer. 2. PLCs are designed to be operated by plant engineers and maintenance personnel with limited knowledge of computers. 3. A typical PLC can be divided into three components consisting of the processor unit, the power supply, and the programming device.
1. The elctromechanical switching is a semi-eelctronic switching that acts as a technological bridge between the legacy manual switching and the eelctronic switching (PLC). The modern electronic switching is completely automated and system controlled
